Quick answer
BatchSet's image resizer resizes many images at once — by percentage, a target width or height, or an exact size — free and entirely in your browser, with no signup, upload or watermark. It keeps the aspect ratio (or crop/pad/stretch to an exact size), avoids enlarging smaller images, exports as JPG, PNG or WebP, and lets you download the whole batch as a ZIP. For fixed platform sizes, use the Social Media Resizer.

Yes. Switch to Percentage mode and scale every image to, say, 50% of its original size in one move.
